Pilot lights listed below are factory sealed and
do not require external seals. Lamps • are 6
watt, type S6, candelabra base for use on
110-125 volt circuits.
Enclosures with single pilot covers only can
be equipped with a transformer for each lamp
for higher voltages as shown.
Double device pilot light covers cannot be so
arranged as the transformer occupies the
space of one pilot light.

Application:
Factory sealed enclosures are installed in a
rigid metallic conduit system for surface
mounting adjacent to or remote from
equipment being controlled and are used:
• to prevent arcing of enclosed device from
causing ignition of a specific hazardous
atmosphere or atmospheres external to the
enclosure
• in industrial areas such as chemical plants,
oil and gas refineries, paint and varnish
manufacturing plants, gasoline bulk loading
terminals, grain elevators, grain processing
industries, coal processing or handling areas,
or metal handling or finish ing areas where
atmosphere may contain hazardous gases
and/or dust
• in non-hazardous areas where sturdy,
durable enclosures are required
• in conjunction with magnetic starters or
contactors for remote control of motors
Manual motor starting switch enclosures are
used:
• for manual starting of small ac or de motors
• to provide manual starting and stopping
and, in the case of units with heaters, motor
running protection

Features:
Factory sealed devices have many distinct
advantages:
• reduce installation problems
• eliminate external seals
• lower installation costs
• improve safety
• are used with general purpose snap and
pushbutton type switches
• standard neoprene covers for front
operated pushbuttons. Prevents
accumulation of dirt and entrance of water
around operating shafts
• mounting lugs and taper tapped hubs with
integral bushings
• large machine screws for fastening covers
to bodies
• lockout provisions on front operated push
button (marked "STOP" and " OFF" ) and

• lockout hole for padlock having
provided when used with covers for front

• on enclosures with front lever and side
rocker type operating handles, threaded type
shafts and bushings are used to ensure
flametightness
